Unpacking / Installing / Replacing Power Supplies
The switch ships with one power supply (820 Watts) standard; order the second Power Supply for an additional
820 Watts.
Note
: The switch supports dual redundant power supplies, and they are hot-swappable. You can apply the AC
power cord to any AC receptacle of the switch. If only one power supply is installed, it can be installed in either
bay. The table below refers to the specification of the input/output voltage to the switch; use the following
information to order the AC power cord.
Unpacking Power Supply
The optional second power supply is packed separately, if ordered. Unpack the optional second power supply and
save the packaging for possible future use.
